If you are still trying to find some of the best air conditioners today, the Honeywell CO30XE Portable AC is among the best evaporative air conditioner since the air cooler offers indoor use and outdoor use in an energy-efficient manner.

Why We Like It – Honeywell CO30XE Portable

The Honeywell CO30XE Portable AC is one of the best air conditioners that can spice up your backyard experience by treating you to a cool breeze even on the driest days. After filling up this device with water and ice you will be able to experience the cool air whenever you need it and you can even use it indoors.

  • Has a remote control so you can control it from a distance
  • You can set up a timer for up to 7.5 hours
  • Customers claimed that it was a bit too loud


The evaporative air cooler uses a combination of water and ice to produce a cold airflow that keeps you refreshed during summer days. It has a detachable water tank, so when it is time to refill the air cooler you can easily remove the compartment. This cooler can cover an area of up to 320 sq ft so you will be able to share the AC with whoever is around you. Similar to the Honeywell CO25AE indoor/outdoor evaporative air cooler that can service an area of about 300 sq ft.

Energy efficiency

Since the Honeywell evaporative air cooler relies on water to bring on the coolness, it won’t take up as much electricity as other models that use compressors. The water tank holds up to 7.9 gallons of water so it is sure to last a while before needing its next refill. An even bigger tank capacity is found in the Honeywell CO48PM which holds up to 10 gallons and allows for a hose connection. If you would like to compare this with other portable air conditioners, first have a look at a more compact option such as the Hessaire MC18M.


The Honeywell air evaporative coolers take the warm air coming in, and use the water and ice you provide to make the breeze more enjoyable for you and those around you. Surprisingly, this particular model does not have a filter, but you can still maintain it by cleaning out the honeycomb cooling media so it is always functioning properly. If you aren’t feeling this design for any reason, there are other alternatives that we feel are also worthy of investing in such as the Luma Comfort EC111B.


The model CO30XE is backed by Honeywell, a company that has been progressively making its products better for over 10 years. These portable evaporative air coolers have been built to withstand outdoor and indoor conditions making them extremely versatile. Even in low humidity, this swamp cooler can still provide a pleasant experience for you so the heat does not torture you. If you are content with what you’re reading of this product so far, feel free to steer the ship and check out other similar products such as the Hessaire MC37M or the Honeywell HL09CESWK portable air conditioner.


Investing in the CO30XE indoor/outdoor evaporative air cooler reassures you that you can feel better about the weather however intense it may be. Although you will want to make sure that you have access to ice at all times to achieve maximum coldness. Customer reviews from verified purchases revealed that they felt that the unit was a bit on the louder end, and it seemed to work better outdoors rather than indoors so take these factors in mind before moving forward with your purchase.

Honeywell CO30XE Portable Wrap Up

The Honeywell CO30XE Portable AC brings evaporative cooling to a 350 sq ft area both indoors and outdoors. As long as you equip it with a large amount of ice, you can enjoy the breeze for a significant amount of time and you will be able to freely adjust settings through the remote control provided. Using the programmable timer you can turn it on and forget about it and simply enjoy the cold breeze it will produce.
